#4 Gum Disease - 6 Surprising Reasons You Are Not Performing Well
11 Nov 2025 · 14 min
Dr. Anne Truong (host) explains how common gum disease can contribute to erectile dysfunction via systemic inflammation that damages the endothelium, reducing nitric oxide production, promoting plaque and clotting in blood vessels, and thereby reducing penile blood flow. She links lifestyle factors (poor diet, smoking, lack of exercise, high blood sugar/high blood pressure) and aging to decreased nitric oxide, and recommends daily oral hygiene (brush, floss, electric toothbrush), a Mediterranean diet, and high-intensity interval training (about 1 hour, three times weekly) to help preserve vascular function. The episode also promotes a paid membership "Modern Man Club" offering coaching, content, and community to address ED.

Well, hello there, modern man. Today I'm going to talk about gum disease and how it's related to ed. Something as common as gum disease. Like yes, yes, you. That can actually affect ed. So guys, if you're not brushing, you're not flossing. And when you do brush, you have a little bit of bleeding, well, you're going to have some issues because that creates inflammation. So stay tuned for the whole episode because I'm going to talk about how the blood vessels get inflamed and what goes on when the endothelium or the lining of the blood vessel is not working well and how it reduces blood flow and that then reduces blood coming into the penis, causing ed. So let's dive into this. So gum disease, it's very common as we know and it happens every time you brush your teeth and then you have some bleeding and then you have some swelling and sometimes even some pain. I have to say I'm not the best person at flossing every day. I have to admit. I floss about three times a week if I'm good and if I'm on vacation, probably not as good as I should be. But I do brush and every day and morning and at nighttime. But when you have gum disease, it actually causes inflammation of the gum. That's why you start bleeding. Then bacteria sets in there. So when bacteria gets into the gum, it actually won't, will go to the, your blood into the blood system. When it goes to the blood system, it will then affect the endothelium. Now the endothelium is the lining of the blood vessel. That is the lining that the blood flows through. So I'm going to show you on this picture that I have here that will show you the endothelium, those that can see this on YouTube, you see that the endothelium, the one cell lining on the innermost layer of the blood vessel, that's where your blood is flowing in and out. And then the middle part of the blood vessel is the smooth muscle. And the smooth muscle is what contracts and relax and it is affected by nitric oxide. So when nitric oxide is produced by the endothelium, it relaxes the smooth muscle. And that's how the smooth muscle relax and contract. That's how you hear the sound, you get the blood pressure reading of the top number, which is a dog and bottom number diastolic. The, the top number is when you're the blood vessel relax and the smooth muscle of the blood vessel relax, you get that top number. And then when it contracts is when you get the the bottom number. And when the elasticity of the smooth muscle of the blood vessel doesn't relax as well, that's when the pressure is a little bit stiffer and that's when you have a higher reading of the blood pressure. I don't want to get on straight, but essentially how you get at high blood pressure is because the elasticity or the inflexibility of the smooth muscle affect how it expands and contract. And when you have high blood pressure, it means that you have decreased elasticity of the smooth muscle. So how the heck does it affect ed? Right. Well, when you have inflammation, such as something as simple as gum disease, it affects the barrier, affect the function of the endothelium. And I will show you on this next slide right here. So the endothelium, the endothelial cell actually generate produce nitric oxide. And we know that nitric oxide is good for blood flow, it relaxes mood muscle and it also act as the barrier as well. And it also prevent excessive inflammation. And it also produces prostacycline, which is an anti inflammatory substance. However, when you endothelium is not healthy just from being having inflammation or gum disease or even high blood sugar or a poor diet, or even not even exercising and having high blood pressure and smoking, it activate the oxidation cycle which is the ros. And then it loses the production of nitric oxide and then becomes more inflamed. So when it becomes more inflamed, the barrier start to be broken and then toxins start to go into the smooth muscle layer of the blood vessel, creating something like this picture here that I'm showing. Because when your endothelium is damaged, such as my high blood pressure, like I talk about in and saturated fat, which is in a diet full of fried food and high carb and pastry and smoking, it actually will damage endothelium. And then the cholesterol and the calcium seep into the muscle layer, which then create plaque like substance, a plaque, it's like a nodule, which then block the flow of, of the blood flowing in through the blood vessel. Now, endothelium actually prevents the platelets, which are the clotting factor of your blood from clotting. So when it's not working well, there the tendency to clot. So when you have clotting with the plaque, bad things happen. That's when you start having decreased blood flow to the heart or decreased blood flow to the penis. So essentially, when you have inflammation, if you see the top picture here, the endothelium, that lining right there, you have a big opening where blood flows in. But when you have your endothelium is damaged, you can see in the bottom picture and that little hole right there, the little gray hole that you can see right in the picture, it's the only part that the blood can flow through. The rest is infiltrated with plaque, cholesterol and fibrin. So that's why you're not getting enough blood flow. So that's what's happening in the penis, because you're supposed to get blood flow like the top picture, big opening, but then the bottom picture opening like this. So that's all the blood that you're going to get into, into the penis. It's being compromised because the blood vessel itself, which deliver blood, doesn't have as much a big opening for the blood to flow into. That's why you see symptoms of ed. And the first thing that you notice is that you know the penis is not getting as firm as it used to be because you're not getting as much flow in which then expand the corpus cavernosum or the muscle of the penis, which then prevent the blood from flowing out.

So the first sign is really more, you can still get an erection, but you get, you notice there's less firmness. So this interesting slide I wanted to show also is that when you get older, nitric oxide production is also affected as well. It decreases. And the red line that you see is a person, an average person, that your nitric oxide production start to decrease at around age 30, right? And it dropped, drop, drop, you know, it dropped down a slope. But from, you know, 10 to 30, you're good, you're, you had a hundred percent nitric oxide production. However, from this picture here, when you have a poor diet and you're not exercising, even when you're younger, at 20, you still, you have about 70% of nitric oxide compared to a person that has a better diet and exercise. But then it drop it, it slowly decreases as you age. And let's say for instance, if you take a 40 year old person, you go up there, if they're not exercising or not eating well, you only have 40% of nitric oxide production versus a person that exercises at the age of 40. Have about 90, 90% of their nitrous oxide. And you, and also on this picture here that you have, if you exercise and have a good diet, then you don't decrease your nitric oxide until you're the age of 40. So when you do have decreased production, it is slower than someone that does not have, does not have a good diet and exercise. So guys, what you eat count and how you exercise also count? Yeah. What, what type of diet should you eat? A Mediterranean diet. What type of exercise should you do at least three times a week, an hour at each time. I recommend high, high intensity interval exercise. And let's talk about gum disease again. So gum disease is important because you need to brush because it does cause decreased blood flow which then lead to ed. But how do you fight gum disease? What, what your dentist tells you all the time when you're younger is brush in the morning, brush at night and floss daily as much as you can and you know you're doing well. When you're brushing your teeth, you're not bleeding. I recommend that you use an electric toothbrush that will actually clean a lot better and it also go, you know, deep inside to the, the root of the tooth as well. Just simple things like that will actually go a long way. Never underappreciate things that we do on a daily basis, guys, because it does count. So stay tuned for the next episode and I will talk more about a surprising reason causes of ed. I'll see you next episode and don't.
